I see, you use { CTL_NET, PF_ROUTE, 0, 0, NET_RT_IFLIST, 0 };
I'd suggest to use getifaddrs(3), it uses more modern sysctl
NET_RT_IFLISTL, note the L at end. And the library function
takes the burden of parsing the stuff.

Yes, mibII/ipv6.c is the place where build is broken right now, since
struct ifaddr is now hidden from userland programs. struct ifnet is
still visible, but soon to be hidden, too.
Is it possible to disable compilation of deprecated IPV6-MIB implementation
at compile time? It could be that would be just the right solution for
future FreeBSD versions, instead of putting yet another ifdef into this
awful pile of ifdefs, that I see in ipv6.c :)
